Age gaps between kids? Is there a gap too big?

I have three children - DD 20, DS 17 & DS 6.
PROS: Loving relationship between all three. The olders get the chance to do fun 'little kid' stuff without irony. Extra helping hands when needed (not to their detriment obv). They love to 'show off' their little brother. They love showing him and teaching him things from when they were little. DS6 has amazing vocab and understanding.
CONS: Difficult to get me-time; sometimes feel as if I am spreading myself soooo thin (which is ironic given the size of my tush!) DS6 sometimes over-stimulated, and gets frustrated that he isn't grown up too! The olders sometimes get overwhelmed by his attention (always make sure I intervene when that happens).
SUMMARY: Our family line up wasn't exactly planned, and it can be difficult to juggle, but honestly - it is amazing and I wouldn't change it.

My DP has a sister that 16 years older then him. They are very close but their relationship sounded more like a nephew aunt.

I have siblings 2,5 and 8 years older, we all fought like cats and dogs.

There is 8 and 10 years between DSS and my 2 sons. We have always tried to prioritised time with each and DSS gets on great with the little ones.

I had a 23 year age gap between my 2dd's.
I'd forgotten how to make a bottle and change a nappy 😂😂

My dsis is 13 years younger than me. We had a different kind of sibling relationship - I used to look after her after school, I took her to the cinema to see the kids films I wanted to watch and I taught her to swim - but we had a lot of fun and we're still very close as adults. My dc love having a young aunt too.

My db, on the other hand, is only 2 years older than me and we spent as much time fighting as we did playing together. We have more shared experiences from growing up but I wouldn't say our relationship is better for being closer in age.

My mum got really mad at me for describing my older brother, who left for university when I was four, as "more like a young fun uncle". But yeah, I don't have tonnes of memories of living with him.

I had an almost three-year but actually two school years age gap with my sister and it was a pain in the arse because she was always mega angsty about her exams, and the ones I was doing at the same time weren't as important as hers.

So my message is: 1) don't put any expectations on their relationship and 2) don't let the older ones be superior pricks!

I have 2 children, my eldest 14 and my youngest is 2 and I worried about the age gap. Honestly it's been wonderful and they are so close. Sometimes hard when thinking of things to do to keep everyone happy but overall love the age gap!

Me and my siblings are 16 and 12 years apart. I think it was a big enough difference for it to work. They were independent and old enough to understand that I was little. However, there is no right age gap. Nothing is guaranteed.

My eldest is 15 and younger two 5 & 1.

The only things we do they all enjoy are zoos or going out for breakfast.

I prioritise spending time with each of them individually and I've taken my eldest on a couple of city breaks just the two of us.

Last year I dropped him and a friend off at Thorpe park and took the middle one to LEGOLAND. There's ways of doing it 😊

Our eldest is 10, also have a 2.5 year old and currently pregnant with our youngest who is due next month. Eldest loves playing with her 2.5yo sibling, adorable seeing how much they love each other, altho they do at times annoy each other (as most siblings do, regardless of age gap). If you really want another child, I would say go for it! Close age is never a guarantee of a good sibling relationship anyway. I'm much closer to my 4.5 years younger sibling than I am to my 2 years older sibling. 🤷
